Beyond the Headline
Kalo Gold Corp. reported on July 8, 2026 that ongoing soil geochemistry, prospecting, and trenching programs continue to refine drill targets across the Wainikoro target area in its 100%-owned Vatu Aurum Project, Vanua Levu, Fiji.
Key highlights are as follows:
- Mercury Anomalies Support the Epithermal Model
Recent soil programs have identified several discrete mercury anomalies that occur near the convergence of major regional structures interpreted to have acted as pathways for hydrothermal fluids during mineralization. Structural intersections of this kind can form dilational zones of enhanced permeability and are a recognized focus for fluid flow in epithermal systems.
The Company notes that mercury is a well-recognized top-of-system pathfinder in low-sulphidation epithermal systems, concentrating in the shallow, cooler upper levels and lateral halos. Its presence is therefore consistent with a preserved, relatively un-eroded level of the system. This interpretation also suggests that any boiling or precious-metal zone may lie beneath the current level of exposure and therefore remains a priority exploration target.
- Quartz Veins Expand the Target Footprint
Prospecting and mapping are reported to continue to identify quartz veins across Wainikoro, including within and adjacent to several magnetic-low anomalies defined by airborne geophysics. The association of quartz veining with magnetic lows is consistent with hydrothermal alteration (silicification and argillic alteration) destroying magnetite), making magnetic lows an important exploration vector. Anomalous quartz samples based on detectORETM measurements from 1.2 g/t Au to a high of 5.5 g/t Au were reported but these values need confirmation by fire assay which is in progress. Note see discussion on this analytical technique in my comments on the June 30, 2026 press release.
- Multiple Independent Datasets are Defining Epithermal Drill Targets
As noted by the Company, multiple independent datasets—including mercury anomalies, hydrothermal breccias, low-temperature alteration, quartz veining, pathfinder geochemistry and recent drilling—are converging on the same structural corridors, substantially reducing geological uncertainty and improving confidence in future drill targeting (Figure 1 below).
- Next Steps
Kalo’s exploration team is integrating geological mapping, soil geochemistry, prospecting results, drilling data, and airborne geophysical datasets to further refine priority targets across Wainikoro. Recent comparison of the airborne radiometric potassium survey against the Wainikoro soil XRF potassium data shows a strong spatial correlation, independently validating the field XRF results and reinforcing the interpretation of structurally controlled hydrothermal alteration along the fault and graben boundaries defined by the airborne magnetics.
Ground geophysical surveys are being designed to define subsurface structures, alteration zones and potential fluid pathways beneath shallow cover. These results will be integrated with existing geological, geochemical and drilling datasets to prioritize the highest-confidence drill targets across Wainikoro.
Comment
Kalo continues to complete good baseline geological, geophysical, geochemical, prospecting and rock sampling to characterize these low sulphidation epithermal systems and outline drill targets. The mercury anomalies in particular confirm that they are likely at or near the top of the epithermal system hence any boiling or precious-metal zone may lie beneath the current level of exposure and therefore remains a priority exploration target for Kalo.

Magnetic lows are outlined by blue dashed lines and vein and structural orientations are shown by orange arrows. The silicified, quartz-veined andesite sample that returned 5,505 dU (~5.5 g/t Au estimated) lies within a magnetic low adjacent to the Nubu Graben Fault (from Kalo Gold Corp. press release July 8, 2026).
